The Akulov-Volkov Lagrangian, Symmetry Currents and Spontaneously Broken Extended Supersymmetry

open access: yes, 2001
A generalization of the Akulov-Volkov effective Lagrangian governing the self interactions of the Nambu-Goldstone fermions associated with spontaneously broken extended supersymmetry as well as their coupling to matter is presented and scrutinized.

The Use of the Cognitive Behavioral Therapy for the Treatment of Migraine and Tension Type Headaches

open access: yesBilişsel Davranışçı Psikoterapi ve Araştırmalar Dergisi, 2015
Headache, which affects a large part of the community and causes loss of workforce, is gaining importance in terms of the burden which it brings on the society, by its function of restricting individuals social activities as well as increasing the health

A Multi-Agent Control Architecture for a Robotic Wheelchair

open access: yesApplied Bionics and Biomechanics, 2006
Assistant robots like robotic wheelchairs can perform an effective and valuable work in our daily lives. However, they eventually may need external help from humans in the robot environment (particularly, the driver in the case of a wheelchair) to ...

On some mean value results for the zeta-function in short intervals [PDF]

open access: yes, 2013
Let $\Delta(x)$ denote the error term in the Dirichlet divisor problem, and let $E(T)$ denote the error term in the asymptotic formula for the mean square of $|\zeta(1/2+it)|$. If $E^*(t) := E(t) - 2\pi\Delta^*(t/(2\pi))$ with $\Delta^*(x) := -\Delta(x)

Rheological Characterization and Performance Evaluation of Magnetorheological Finishing Fluid

open access: yesJournal of Applied Fluid Mechanics, 2020
The novel controllable behaviour of magnetorheological (MR) fluid is the backbone of magnetorheological fluid-based finishing processes. MR fluid-based finishing processes facilitate better control over finishing forces as the stiffness of MR finishing ...

Progress in existing and planned MST radars [PDF]

open access: yes, 1986
Radar systems are described which use two different wind measuring techniques: the partial-reflection drift technique and the mesosphere-stratosphere-troposphere (MST) or Doppler beam-swing radar technique.

Electronic Effects of the Substituents on Relaxometric and CEST Behaviour of Ln(III)-DOTA-Tetraanilides

open access: yesInorganics, 2019
Three different 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetamide (DOTAM) derivatives bearing as amide N-substituents phenyl, p-methoxyphenyl and p-ethylbenzoate groups were synthesized and the 1H and 17O NMR relaxometric behaviour of the Gd(III ...

Transmission of Renormalized Benzene Circuits

open access: yes, 2015
The renormalization equations emerge from a Greenian-matrix solution of the discretized Schrodinger equation. A by-product of these equations is the decimation process, which enables substituted-benzenes to be mapped onto corresponding dimers, that are ...
